Hey guys, complete beginner here.. Im trying to access and return the users information of the members of a group. I am not so sure where I am going wrong and I'm trying to understand the log instructions but I can't quite understand where I'm going wrong. Ive seen "Sql error column doesn't exist in where clause".. tried to change the code and finding undeclared variables too.
The system is that a user creates a hobby and that hobby becomes the group. ie 'my hobby is skiing and then a group of skiing is created'. So I have a user_hobbies model of course and everything is work, but I can't quite work out how to access the information of the user from the DB and display it in the blade.
Any help appreciated.

You have typo on query builder.
$users = DB::table('users')
->join('user_hobbies', 'users.id', '=', 'user_hobbies.user_id')
->where('user_hobbies.hobby_id' == $group_id) // This line
->select('users.*')->orderBy('first_name', 'ASC');
It should be
$users = DB::table('users')
->join('user_hobbies', 'users.id', '=', 'user_hobbies.user_id')
->where('user_hobbies.hobby_id', $group_id)
->select('users.*')->orderBy('first_name', 'ASC');
And make sure you use === instead of == for explicit comparation in PHP. It will cause a Type Juggling. I assume your blade file is correct since i dont know what's inside the $user object
